shown: connection with? Figtli diagram 1 an electriclcircuit' 56 which includes the coils,

of the solenoid 28, also a generatorg58 iswitchl Qsdes rab yit qc-eted rei temin nelawhereof will be tively to the control valve 18, also a second switch 62 which may be'locatedin close proximity to said controlling means. i

' :The'generator 58 is shown coupled with a turbine 64 or other power generating device located in a conduit 66, the supply of fluid controlled by the pivot valve 1. I

- With the above arrangement it will be obvious that the opening of, the valve 1 as here- 7 inbefore describedso as to supply .fluid to "the turbine 64 starts the generation of electricity in the circuit 56 and energizes the solenoid 28. As long as there current in;

said circuit fiuid'will continue to flow to said generator, also, as long as thecircuit 56 rema ns closed and fluid continues to flow through said conduit 66 to the turbine so as to generate current the pivot valve will remain open.

To close the valve 1, either the switch 60 or the switch 62 may be opened or should anything unforeseen happen to said circuit or any parts included therein which would result in interrupting said current-supply the pivot valve will automatically close upon the deenergizing of said solenoid. It is to be understood that the invention i not. limited to the specific embodiment shown herein.

*Iclaim: i In combination, a pivot valve, fluid operated means for'opening and closing said pivot valve, a control valve for said fluid, manual means for operating said control valve from a proximate point, electrical means for operating said control valve from a remote point to maintain said control valve in aposition to hold said valve open, Iweight means for returning said controlvalve to said closed p0 sition upon the deenergizing of said electrical means, and means for cushioning said control valve uponv its return to normal position.

In testimony whereof, I have signed my name to this specification.
